MECHANISM FOR RAISING OR LOWERING FOOTBOARDS ON OPEN CARS.

SPECIFICATION formingpart of Letters Patent No. 662,006, dated November2 1900.

Application filed Ptember 7, 1900. Serial No. 29,282. (No model- T0 atw/tmn it WMLZ/ concern:

Be it known that I, ROBERT E. LINTNER, a citizen of the United StatesofAmerica, residing at East Pittsburg, in the county of Allegheny andState of Pennsylvania, have invented certain new and usefulImprovement-sin Mechanism for Raising or Lowering Footboards on Open Cars; and I dohereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to certain new and useful improvements in amechanism for raising and lowering the footboards on open cars.

The invention relates particularly to that class of open or summer carsin which the footboards are each composed of one piece and extend alongthe sides.

The object of my invention is to provide a simple and positive means ofraising or lowering either foot-board from the platform at either end ofthe car. By this means the motorman or conductor will have full controlof the i'ootboard without having to leave the car.

With this object in View the invention finally consists in the novelconstruction, combination, and arrangements of parts, as will be fullydescribed in the accompanying specilication.

In describing the invention reference is to be had to the accompanyingdrawings, wherein like detail parts are designated by numerals of likecharacter in the several views, in which- Figure 1 is a side elevationof an open summer-car having my improvements attached thereto. same.Fig. 3 is a plan view of the footboards and operating mechanism detachedfrom the car. Fig. 4 is a side elevation of the footboards and mechanismshown partly in section on the lineA B of Fig. 3. Fig. 5 is an endelevation of the footboards and mechanism.

Referring to the drawings, the numeral 1 designates an open street-car,2 and 3 the platforms, and a and 5 the footboards thereof. Attached toand extending across the under side of the carbody near the platformsare the frames (5, which form a part of and are intended to confine themechanism. Each of these frames are provided at its ends with a pair ofFig. 2 is an end elevation of the upwardly-projecting abutments 7, whichterminate in rounded portions 8. These frames are provided near theiredges withantifrict-ion-rollers 9,andupon these rollers are mounted theframes 10, which are held in contact therewith by means of lugs 11 uponthe main frame. Pivotally attached to the ends of each of the frames 10is a pair of bent levers 12, which are connected at their outer ends toand form supports for the footboards 4 and 5. Above the frame at one endof the car and attached to the body thereof is the small pulleys orsheave-wheels 13, 14, 15, and 16. At the opposite end of the car abovethe frame is attached a similar set of wheels 17, 18, 19, and 19.Extending down through the platform 2 is the shaft 20, which is providedwith a ratchet-wheel 21, and small drum 22, said ratchet-wheel beingadapted to engage with a dog 23, pivotally attached upon the platform.The opposite end of the car or platform is provided with a similar dog24: and shaft 25, carrying a ratchet-wheel 26 and drum 2'7.

The shaft-drums at each end of the car are connected to one another by achain 28. This chain passes over the pulley-wheel 13, under the wheel14:, connecting to the frame 10 at 28, thence under the wheel 15, overthe wheel 16, to the wheel 17, over this wheel and under the wheel 18,connecting to the frame 10 at 29, thence under the wheel 19 and over thewheel 19.

In the views shown the footboard upon the near or left side of the caris shown down, while the one upon the right side is shown up or in theposition it assumes when not in use. Now when it becomes necessary toreverse the boards the dog 23 is released from the ratchet-wheel 21. Theoperator at the opposite end of the car then applies a crankhandle tothe shaft 25 and rotates said shaft to wind the chain upon the drum 27.This movement of the chain causes the frames 10 to shift their positionsto the left, and in shifting their positions the bent levers 12, whichconnect the boards with the frames, engage with the rounded ends of theabutments 7, thereby raising the board upon the left and lowering theboard upon the right. The dog 24 is then placed into engagement with theratchet-wheel to lock the boards in position or prevent the chainunwinding from the drum. It will be seen that by this means the boardsmay-be raised or lowered from either end of the car. The chain may becaused to pass over additional pulleywheels after it passes from thepulley 16 to the pulley 17, so as to carry it along the side of the carinstead of diagonally across, as shown. Other modifications of thedetail parts may be made without departing from the principles involvedin the invention.

Having thus fully shown and described my invention, what I claim as new,and desire to secure by Letters Patent, is-

1 In a mechanism for raising and lowering the footboards on openstreet-cars, the combination with the car-body and the footboards, ofsupports arranged beneath the car-body, laterallyadjustable framesmounted upon said supports, supports extending inwardly from saidfootboards and pivotally attached to said adjustable frames, fixedabutmen ts engaging said footboard-supports, and a means of adjustingsaid frames from alternate ends of the car successively to raise one ofsaid boards and lower the other at the same time.

2. In a mechanism for raising and lowering.
